I tried Ion Fury.
Its fun, but boring.
Actually its not much fun. Its basically a super charged Duke Nukem 3D but for some reason I didnt enjoy the gameplay. Very simple classic violence and exploring, which most of us have grown out of at this point.
Im refunding it.
I've noticed virtually zero freebies from Steam which is quite tight fisted given how big they are. If lil' GOG can give away multiple games, $billionaire GabeN should be able to. Heck, even the CCP-fronted Epic gives stuff away.
